Martin, with 4.4 I get messages like device-mapper: table: 253:4: adding target device sdq caused an alignment inconsistency: physical_block_size=4096, logical_block_size=512, alignment_offset=0, start=0 when I use device mapper multipath on a scsi disk on a FlashSystem-9840 scsi disk. The disk has a quite interesting layout (physical block size=4k, logical=512) blockdev --getbsz /dev/sdq 4096 blockdev --getss /dev/sdq 512 blockdev --getpbsz /dev/sdq 4096 the disks seems to work ok, though. Any ideas? Christian -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
